Novavax NVAX Stock Plummets 11.4%: Sanofi Vaccine Deal & Q3 Results Explained (2025)

Novavax (NVAX) stock dropped by 11.4% after a significant deal with Sanofi and the release of its Q3 results. Is this a sign of a major shift in the investment narrative? Let's dive in!

In November 2025, Novavax finalized the transfer of its U.S. marketing authorization for its COVID-19 vaccine to Sanofi. Simultaneously, the company reported its third-quarter results. These results included a revenue of US$70.45 million and a net loss of US$202.38 million for the quarter. However, the report also showed a net income of US$422.78 million for the nine months ending September 30, 2025.

This collaboration with Sanofi not only provided Novavax with a US$25 million milestone payment but also sets the stage for future revenue through milestones and royalties. This is based on product commercialization and future developments under the agreement.

We'll now examine how this completed transfer to Sanofi, along with the milestone payment, could reshape the investment narrative surrounding Novavax.

The main risk continues to be the reliance on partners meeting their regulatory and market goals on time.

The most significant recent event is the November 2025 announcement, which finalized the transfer of Nuvaxovid's U.S. marketing authorization to Sanofi. This move triggers new financial inflows for Novavax. It also increases its dependence on the outcomes delivered by external partners. This directly links revenue stability to Sanofi's commercial performance in a highly competitive market. The future impact on Novavax will largely depend on...
